To all whom it my mama:

Be it known that I, AIs'TON MILL, a citizen of the United States,residing at Cincinnati in' the county" of Hamilton and State of Ohio,have invented certain new and useful Improvements in Apparatus forsterilizing Canned Goods, of which the following is a specification; 1

My invention relates to an improved apparatus for. sterilizing cannedgoods. One of the objects of my invention is to provide an apparatuswhereby canned goods in hermetically sealed packa 'e's, preferably cans,can be continuously f into and out eta closed chamber, Sub ec'ted totheac'tion of steam or heat during its travel throu' h the chamber, withmeans for continuous y rotating or :revolving the cans during theircourse of travel through the chamber.

Another object of m invention is -.to provide means for lateral yagitating the cans during their 'course of travel throughthe 80 course.-

chamber. a

Another object of my invention-is to-provide a sterilizingapparatus,having a sealed, steam orheating-ehamberwith anmner cylind'erupon whiehthe cans travel durin a portion of their travel-from the inletto he outlet,: and a series of bars between which the cans are vfed andcarried in a spiral Other features of my invention relate to specialdetails of construction,"more fully set' lorth in the description of theaccompanylng drawings -forming a part of. this specification, in -wich': I 3

-To move the cans from one end .of-the cylinder 1 to the opposite end inthe spiral groove-way 6, the rods are rotated carrying with them thecans, permitting of a continuous feedinto and out of the cylinder 1.These rods are carried around the inner cylin-der," as follows :-10, 11,represent gear Wheels fined to or formed integral with the I wheels 7,8, respectively, meshing with pinions '12, see Fig. 4, the pinionmeshing with gear. 11, not being shown in the drawings; said pinionsbeing fixed to shafts 13, 14,

To accomplishthis,

suitable valve mechanism is emp oyed and controlled'by the main drivingshaft,- whereby the action may be continuous and intirne movements withthe b'ars within the c'llnder,- so as to feed each can between the ars.
